Hybrid tea rose plant named &#39;Ruirorap&#39;

ABSTRACT

A new and distinct Hybrid Tea Rose plant having attractive large Red flowers.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct variety ofrose plant of the Hybrid Tea rose class, which was created by crossingas seed parent an unnamed, undistributed seedling and as a pollen parentthe variety known as ‘Tina’. The varietal denomination of this new roseis named ‘RUIRORAP.’ The new variety was grown from a grafted cutting inThe Netherlands.

SUMMARY OF THE INVENTION

[0002] Among the novel characteristics possessed by this new varietywhich distinguishes it from its parents and all other varieties of whichI am aware are its bud shape and color.

[0003] Asexual reproduction by propagation of grafting of the newvariety as performed in De Kwakel, The Netherlands shows that theforegoing and other distinguishing characteristics come true to form andare established and transmitted through succeeding propagation.

COMPARISON WITH PARENTS

[0004] Among other respects, the new variety differs from its parents inflower color, inasmuch as the seed parent has Pink flowers and thepollen parent has small Yellow flowers whereas the new variety has largeRed flowers.

BRIEF DESCRIPTION OF ILLUSTRATION(S)

[0005] The accompanying illustration shows a typical specimen of the newvariety depicted in color as nearly true as is reasonably possible tomake the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

[0006] The following is a detailed description of the new variety withcolor terminology in accordance with The Royal Horticultural SocietyColour Chart (RHSCC). The terminology used in color description hereinrefers to plate numbers in the aforementioned color chart. Phenotypicexpression may vary with light availability, environmental and culturalconditions.
